QSO Today Online Expo August 8, 2020: More 10 GHz Information   Leave a comment

The First Virtual Ham Radio Exposition

 

Some additional information to supplement my presentation called “Building and Contesting on 10 GHz.”

This is not a complete listing of “microwave amateur radio knowledge” but it is a one-page resource to help you get started.

The first thing I would recommend is to find and join your local VHF and above ham radio club. There are clubs that focus on microwave technology and operating all over the world – find yours to meet new people, learn new things, get a rig going and join the fun!

Microwave Update (MUD)
One of the best places to meet active microwave band hams and learn more about the SHF ham bands is the Microwave Update (MUD). The event is sponsored by various clubs around the USA.

The printed papers (Proceedings) are available from the Lulu print-on-demand service.

The IF Radio

144 MHz and 28 MHz all mode transceivers

All-mode transceivers become the IF on the uWave bands

All-mode transceivers become the intermediate frequency (IF) stage in a microwave transverter system. I like to call the IF rigs the human to “transceiver interface” because this is the unit we use to tune the operating frequency, hear through the speaker and transmit audio via the microphone. Usually the IF radio also initiates the receive to transmit change-over as well.

It is important to know that IF radio performance does not affect overall performance on the microwave frequency.

In other words, fancy filtering, special ovenized oscillators and even CW or SSB filtering are not mandatory. While all those features and functions can enhance enjoyment, it’s the transverter at the microwave frequency that determines performance for the microwave station. In fact, I have two Yaesu FT-817s. One is equipped with CW filters, one is not. Sometimes, because stations often drift, the IF radio with the filter may not be able to hear the other station because the stations have drifted beyond the receiver passband. I normally bypass the filter on my IF radios.

But this is also a good thing, since it means inexpensive and even used VHF, all-mode rigs can be used.

Also remember, for transverter use, the transmit power from the IF rig is on the order of a few mW or less. So, if you are able to find, for example, an all-mode 2m rig being sold “for parts or repair” – that may be a viable candidate for an IF radio.

On most of my IF radios, I added a “convenience box” interface. This box converts all the interface connectors to ordinary RCA jacks. This is very handy in case my IF radio breaks: I can quickly swap any IF radio and swap it almost instantly, regardless of the IF radio model. My IF radios include a Kenwood TR-751, Yaesu FT-817, Radio Shack HTX-10, and some others.

Here is a picture of the convenience box on my FT-817 . . .

The locking toggle switch is used to lock the IF rig into transmit (PTT Lock) mode to make it ready to send a carrier/beacon tone. Center right: Above, the yellow LED indicates “Key Condition.” The locking toggle switch is closed and locked to key the transmitter after the PTT is locked into transmit. The red push button is used to send CW in case I forget to pack my key or the key breaks in the field.

Essential for Success: Accurate Reference Frequency

10 MHz reference oscillators

To help ensure successful two-way operation on the microwave bands, a stable and accurate 10 MHz Reference oscillator is essential.

This can take the form of Ovenized Crystal Oscillators (OCXO), GPS-Disciplined Oscillators or Rubidium Oscillators. All of my transverters have OCXO units that I calibrate at a friend’s lab. Once set, I can depend on being very close to the displayed frequency. One secret: I keep the reference oscillator continuously powered throughout the contest weekend.

Although some club members have rigs using a rubidium or GPS standard, my OXCO-equipped rigs are able to match those other, more sophisticated radios without any problems.

Improvement Paths

Receive

10 GHz Receive Pre-Amplifier (LNA)

Low Noise Amplifier (LNA) for 10 GHz

Low Noise Amplifiers (LNAs) can be found as Low Noise Block converters (LNBs) for Ku-band (12 GHz to 18 GHz) satellite TV receivers. Noise figures at or better than 1dB and 20dB-plus gain can be achieved. The modifications are easy and can be done without test equipment. Chip, N6CA published an example on his webpage.

Antennas

Dish Envy

2-ft Dish vs 6-ft Dish

I call the picture above “Dish Envy.” On the left is Dick, WB6DNX with his 2-foot prime-focus dish. On the right is Robin, WA6CDR with his 6-ft dish.

Most beginning 10 GHz ops start with discarded and usually free satellite TV offset-fed dish antennas. But 24-in. diameter prime focus dish antennas or 24- to 30-in. offset feed antennas work better. Paul Wade, W1GHZ is an excellent online “microwave antenna handbook” – a great resource for hams.

Amplifiers – SSPA, TWTA

KH6WZ 10 GHz SSPAs

10 GHz SSPAs

It is amazing what one can find on eBay and other online auction sites.

High power amplifiers – Solid State Amplifiers (SSPA) and Traveling Wave Tube Amplifiers (TWTA) as well as other materiel for the microwave bands such as waveguide, SMA, Type-N and other connectors and assemblies are becoming available to just about anyone.

As mentioned briefly in the presentation, you must be careful when bidding or buying an amplifier for the 10 GHz ham bands, since some non-ham band amps may not be easy or may be impossible to convert to the 10 GHz ham allocation.

However, there are also many 10 GHz amplifiers that can be re-tuned (“snowflake tuning”) or used as-is. The term snow flaking is used when describing the tuning of microwave amplifiers or other surplus items. A step-by-step article about snow-flaking a surplus amplifier for 10 GHz is posted on the San Bernardino Microwave Society (SBMS) website. See “10 GHz Qualcomm Modification Notes” and “Modifying the Qualcomm 1W Ku-Band PA for use on 3.4, 5.7 or 10.3 GHz.”

When snow-flaking, a small wooden stick with a tiny speck of copper foil is touched and moved around the traces of an RF section while monitoring RF power. Watching for peaks, the small probe is removed, and a piece of copper foil is soldered in that location.

It is tedious but can be fun and rewarding when the job is completed and you have more power on the X-band.

An excellent example of a small amplifier often found on eBay can be used without modification is the Harris-Farinon Model SD-108175 / 076-108687-001 solid state power amplifier (SSPA). I have several of these in use, and the power varies from about one watt to three watts on 10368 MHz.

See “Harris-Farinon 10 GHz Amplifier for Amateur Radio Use” in the References section below.

The good news is that many microwave ham bands over-lap the commercial or other non-ham service allocations (such as Wi-Fi, Bluetooth and Industrial, Scientific, Medical [ISM]), and amplifiers intended for these services can often be used as-is without modifications to the RF section. No tuning necessary.

In any case, all amplifiers will require a power supply (various voltages), power supply sequencing and high power transmit/receive changeover to integrate into a “beginner system.”

Sequencers: Protect Your Investment

Sequencer Demo at Maker Faire

Sequencer Demo at Maker Faire

When moving to higher than “driver power” (milliwatts), it is important to protect the receiver and amplifier circuits by delaying the time between receive and transmit. The delay needed is only a few milliseconds, enough time to allow the relay contacts to close and settle before the change from receive to transmit happens.

A sequencer automates switching various stages in this specific order:

  1. Antenna relay
  2. Transverter enable
  3. Power amplifier enable
  4. Transmit enable

The order is reversed when going from TX to RX.

In my Maker Faire display, pictured above, the W6PQL 4-Event Sequencer is used to drive a large Type-N relay (for T/R) and three high current power relays used to turn on the transverter support functions. It is available as a kit from the W6PQL website.

I have also built and use several sequencers based on Chip N6CA’s “Time Delay Generator” circuit, presented in many years of the ARRL Handbook (1997 and others).

I hope my presentation inspires more hams to try something different. There are many developments and new technologies to explore in ham radio, let’s continue the century-old Ham Radio Tradition in the 21st century style and remind people ham radio is still relevant today!

Not Your Grandpa’s Ham Radio at San Diego Maker Faire October 3 – 4, 2015   Leave a comment

UPDATE — See what Dennis W6DQ and I did for the San Diego Maker Faire! 

 

MakerFaireFlyer1-San Diego

This is our fourth consecutive year as Makers. The 2015 SD Maker Faire team is Dennis W6DQ and Wayne KH6WZ

Our mission is to change the image of ham radio, making it both contemporary and chic in a hi-tech sort of way. We also want to emphasize how ham radio can be used for science and technology education and a possible career path for youngsters.

Amateur, or ham radio has always included teaching-learning-making-modifying-hacking and networking (making new friends) traditions for over a hundred years. We want to remind people this “new Maker Movement” is not really a new idea. Read my LinkedIn Publish post called “The Original Makers” to learn more about this.

We also want to show everyone that ham radio technology changes with the times, and continues to include both past and present to accomplish one thing: Creating ways to communicate voice and data over the ether, without wires.

Here are some of the projects on display – stay tuned for more stories and pictures after the event!

 

By the way – here are 65 reasons why ham radio continues to survive – and possibly thrive – in a world of instant, global communication fro everyone:

October 15 to 18: Microwave Update (MUD)!

wayne yoshida MUD 2015 Banner

Microwave Update, or MUD, is a yearly technical conference for amateur radio experimenters making, modifying, hacking, building, testing and using the 1,000 MHz and up radio bands. Participants from all over the world gather at these events to share information about operating techniques, radio propagation and radio station equipment. One aspect of this event is the buying, selling and trading of surplus parts and assemblies for these frequency bands, since some items may be difficult to procure in some areas. But perhaps the best thing about MUD is socializing and making new friends from all over the world to discuss common interests and goals.

Preparations for the San Diego MUD are still under way. Last weekend, a few San Bernardino Microwave Society (SBMS) members gathered at Dave’s lab to sort and package some prize and give-away items for the event.

The Bay Area Maker Faire 2015 team: Team Leader Brian Yee W6BY and his wife Pat and daughter Stephanie, Dennis Kidder W6DQ, Lisa Gibbons KF6QNG and Paul Zander AA6PZ

We had working, hands-on ham radio projects including Brian’s (W6BY) 10 GHz ham radio transverter system, a radio-controlled tractor/forklift (ZigBee controller) and the big screen used as an electronic sign.

Dennis W6DQ brought several brand new projects this year, including a working Amateur Radio broadband (WiFi) network with seven nodes, a software-defined radio (SDR) system.

I brought a demonstration comparing old and new technology in antenna tuners. It uses light bulbs for a substitute (“dummy”) antenna.

 

 

There’s so much to see and do. Here are some pictures of what I get a chance to see.

 

Always great to see Tenaya promoting Arduino and Arduino related projects and products!

Maker Faire Bay Area is now history. Our booth, “Not Your Grandpa’s Ham Radio” included new projects and demonstrations. This was our fourth year as Makers and the fifth year as visitors to the Maker Faire in San Mateo.

This is a short overview of our display. Stay tuned for more images, stories and videos.

Here is the text from our handout. It answers some of our most-often asked questions:

What are we doing?
Thank you for your interest in our Maker Faire display “Not Your Grandpa’s Ham Radio.” This is our fourth consecutive year as “Makers,” and our goal is to show people what today’s ham radio operators are doing with the newest technology.

Who are we?
We are licensed Amateur radio operators (“hams”).

Is this like CB?
Yes and no. Ham radio is similar in that we use two-way radios and antennas to talk with each other, but hams can communicate using Morse code and computers in addition to voice, and we even have our own satellites. Ham radio requires a license issued by the Federal Communications Commission (FCC) in the US and licensees are required to pass a written test on electronics theory, radio regulations and operating procedures.

How far can you talk?
We can communicate with other ham stations around the corner or across the globe, depending on a variety of factors that affect the way radio waves travel. The equipment we are using operates on frequencies that generally follow line-of-sight paths. However, hams have discovered that signals can be reflected against objects such as buildings, trees, islands and mountains to extend the range. Using these techniques, we are able to contact other stations hundreds of miles away.

What kind of radios are you using?
We are builders and experimenters in microwave radio communications. No commercially-built, “off-the-shelf” equipment for these frequencies exists, so we must build our own equipment, or modify commercially-made equipment meant for other communications services, such as satellite TV, cell phone and long-distance telephone.

How much does this equipment cost?
Like any other hobby, people spend as much or as little as they can afford. Most people involved in ham radio spend as much as any serious stereo enthusiast, amateur photographer or woodworker.

Where can I get more information?
American Radio Relay League (ARRL) and QST Magazine

Urban Workshop Open House – A Hacker Space in Irvine   Leave a comment

I discovered an announcement of this open house the night before the event. The lead came from a Meet Up post from  Make: OC, since I have been displaying at Maker Faire for several years now. It was a very short notice — but I am glad I saw it — especially since the Urban Workshop is less than 5 minutes away from my office.

Steve Trindade is the Founder and CEO of the Urban Workshop.

Urban Workshop is a hacker space, a membership organization where creative and talented people can get together and learn from each other. Urban Workshop provides the tools and support staff to help people build what they imagine.

They have an impressive array of stationary power tools for wood as well as metal, including a laser cutter and CNC mill. They have all types of welding equipment, too. And of course, they have a very expensive-looking 3D printer.

There is a full page of classes on a variety of subjects, including automotive alignments and race car chassis setups, CAD concepts, CNC router programming, electronics soldering basics and Arduino programming, machine tool instruction and more.

The equipment is all high-end, professional gear, and looks brand new.

Click here for more information on Urban Workshop.

Here are some pictures. . . .
